Choose a thermostatically controlled convection panel heater for steady background warmth if you can position it with clear airflow; a timer is useful when you heat the room on a regular schedule. A heater can warm the air, but it will not repair a cold wall or resolve persistent damp or mould. If warmth at one fixed seat matters more than heating the room air, an infrared panel is a different option to consider.
If you need controllable warmth in a bedroom, home office or living area but cannot drill into a wall, consider a stable freestanding convection heater. For a fixed panel, check your tenancy terms and obtain permission before installation.
If an external wall feels cold, check whether damp, recurring condensation or a property defect also needs attention. Extra heat may improve comfort without addressing the cause; government damp-and-mould guidance for England advises tackling underlying problems.
If the heater will run most days, look for a thermostat and a schedule that fit the times you use the room. Compare likely electricity use using the exact heater input, expected running time and your own tariff.
Decide whether you need background warmth throughout the room or direct warmth at a fixed position, then check the heater’s controls, placement and the condition of the cold wall.
| Concern | What to check | Who this matters to |
|---|---|---|
| Steady room warmth | Check the exact model’s room guidance and thermostat, allowing for the room’s heat loss and the space needed for airflow. | For a room used over several hours, I want steady background warmth rather than a short burst of heat; around 31% of consumers put room comfort first. |
| Electricity use | Compare rated input power and whether a thermostat or timer can match heating to occupancy; calculate likely use against your own tariff. | If I heat the room regularly, I want to avoid running the heater when the space is empty. For around 25% of consumers, controlling electricity use is the primary need. |
| Cold-wall condition | Look for recurring condensation, mould, damp patches or signs of water ingress before treating extra heat as the solution. | When a wall remains cold or shows damp, I need to find out what is causing it, not just raise the air temperature; around 25% of consumers put that question first. |
| Safe, flexible placement | Check the model’s clearances, cable reach and mounting requirements; obtain permission before drilling in a rented flat. | In a tight room where I may need to move the heater, I need a safe position without assuming I can wall-mount it. That is the leading concern for around 19% of consumers. |
A higher-output heater can still run for long periods if the room loses heat, and it cannot repair damp, water ingress or a building defect.
Check the manufacturer’s room guidance alongside signs of moisture or damage. If you rent, report persistent problems to the landlord or managing agent in writing.
Electrical Safety First advises leaving clear space around portable heaters; curtains, bedding and furniture can obstruct airflow and create a fire risk.
Follow the exact model’s clearance instructions, keep its grilles unobstructed and do not use it to dry clothes.
Electrical Safety First warns that high-powered appliances, including heaters, can overload extension leads or socket outlets.
Choose a position the supplied cable can reach from a suitable wall socket. If the socket or cable route is in doubt, seek competent electrical advice rather than improvising.
A schedule can avoid heating an empty room, but electricity use still depends on the heater’s input, how long it operates and the room’s heat loss.
Compare the exact model’s rated input and controls, then assess likely use against your own electricity tariff and occupancy pattern.
Dimplex offers installed-style panel heaters with electronic controls, including the PLXE and Alta ranges.
De'Longhi’s slimline convection models are relevant if a non-permanent heater better suits your flat.
Haverland has wall-mounted panels as well as electric radiators, so its ranges should not be treated as one heater type.
This panel heater is relevant if you want room warmth with app-based scheduling and have a suitable place for it. Check the exact installation arrangement before choosing it for a rented flat.

Consider this model if you want a panel heater with app control and a 24-hour timer for scheduled room heating.
Its stated output is 1500 W. Check the manufacturer’s guidance against your room’s heat loss and confirm the required installation clearances.
The product name mentions both wall-mounted and freestanding use; confirm the exact configuration and any supports needed before relying on freestanding placement.
No. A convection panel heater can warm room air, but it cannot repair water ingress, a building defect or mould. If damp or mould persists, investigate and report the underlying problem rather than relying on extra heating alone.
Multiply its input power in kW by the hours it runs and your electricity tariff’s unit rate. A thermostat may cycle the heater off, so continuous operation at its rated input is not necessarily its actual use; room heat loss also matters.
Plan to use a suitable wall socket instead. Electrical Safety First warns that high-powered appliances such as heaters can overload extension leads and socket outlets; check the supplied cable reaches a safe heater position.
Check your tenancy terms and obtain permission from the landlord or managing agent before drilling or making a permanent installation. If the wall is damp or damaged, seek an assessment before mounting a heater on it.
An infrared panel may suit a fixed seating or desk position where you receive direct radiant warmth, but it is not automatically a better way to warm all the room air. Energy Saving Trust explains that infrared heats surfaces in its path; it will not address the cause of a cold wall.
